Logan Gunthorpe cbd27448fa ntb_transport: Fix bug with max_mw_size parameter ... When using the max_mw_size parameter of ntb_transport to limit the size of the Memory windows, communication cannot be established and the queues freeze. This is because the mw_size that's reported to the peer is correctly limited but the size used locally is not. So the MW is initialized with a buffer smaller than the window but the TX side is using the full window. This means the TX side will be writing to a region of the window that points nowhere. This is easily fixed by applying the same limit to tx_size in ntb_transport_init_queue().
